You can adjust the graph view in real time during data collection, or after data collection has 
ended, by applying one of the following actions from the Graph menu. 



 

 – Tap Autoscale Once will 

quickly reset the axes of the currently selected 
graph based on the data. It is an easy way to 
automatically scale both axes. 



 

– Select a region on the graph, then tap 

Zoom In to automatically adjust the axes for 
viewing the selected region. 



 

 –Tap Zoom Out to undo a Zoom In 

and return the graph axes to the previous 
settings.  If Zoom In is used several times, Zoom Out will undo each Zoom In, one at a 
time. 



 

 – Tap Graph Options to manually adjust graph settings. To adjust the 

graph view, change the values in the Left and Right fields for the x-axis and y-axis. 

 

You can manipulate data from the Graph screen or from the Table screen. If using the Graph 
screen, first tap to select a data point of interest or tap-and-drag to select a region of data. Then, 
choose the desired tool from the Graph menu. Upon tapping on the tool, the action will be 
applied to the data. 



 

Strike Through Data and Restore Data

 – Use these tools to ignore/restore selected data. 

Struck data are ignored for analysis and graphing, and the graph will update accordingly. 
To restore all data, tap the Graph menu and choose Restore Data. 



 

 – Use this tool to tag a data point with a comment. After selecting the point and 

tapping Tag Data, a circle will be displayed on the graph to “tag” the data. To add a 
comment, tap in the info box at the right and enter a comment into the blank field. 

 

The Analyze menu on the Graph Screen gives you 
access to additional tools such as tangent lines, 
integrals, statistics, and curve fits. To apply one of these 
tools, tap the Analyze menu and tap to select the desired 
tool. If prompted, select a column or data set to which 
the analysis will be applied. 

Upon enabling an analysis tool, a summary of analysis 
information is displayed at the right. Scroll arrows will 
appear, if needed. Optionally tap the summary to 
display the values on a detail dialog for ease of reading. 

The following analysis tools are available from the 
Analyze menu. 



 

 – The Tangent mode enhances the 

Examine cursor by adding a tangent line and 
numeric display of the slope as you tap different locations on the graph.
